Additional Information

I don't have any includes in my component as you can check in the repo.
Would it be possible to remove vitest and use just jest?

The test itself doesn't fail as you can see:

but it's annoying since it shows 35 errors

Thank you for submitting the issue!

I'm not able to access the repro. Please verify that it's been given public access.

Also, there's a new release for Ionic Framework that might have fixed it. I would also recommend updating the latest version. We fixed a bug that might be similar to this one.
